Garrett flash pyrolysis process

Both the COED process and Garrett Flash Pyrolysis have been "proved" in small demonstration plants and subject to tests designed to establish optimum operating conditions for a particular feed coal, both are claimed to be ready for commercial use. 

The occidental flash pyrolysis process originally called the Garrett process (Sass, 1974 Howard-Smith and Werner, 1976) (Figure 19.4) involves the pyrolysis of the feed coal particles at a temperature not in excess of 760°C (1400°F) in an entrained system to produce a liquid product, char, and gas. 

ORC [Occidental Research Corporation] Also called the Garrett process. A coal gasification process using flash-pyrolysis at approximately 900°C in the absence of oxygen. Piloted by the Occidental Research Corporation in the 1970s.
